Initial Value Slave Host Description
0
R/(W)*² R/(W)*¹ Slave Reset
Performs a reset from the host to the slave. The
host can only write a 1. Writing a 0 to this bit is
invalid. The host will always return a 0 on read
out. Setting the RSTRENBL bit enables a 1 to be
read from the host.
0: The reset is cancelled
[Clearing condition]
When the slave writes a 0, after a 1 has been
read from BMC_HWRST.
1: The reset is in progress.
[Setting condition]
When the host writes a 1.

These bits are defined by the user and are valid
only when set to 1 by a 0 written from the host.
0: [Clearing condition]
When the slave writes a 0, after a 1 has been
read from OEM.
1: [Setting condition]
When the slave writes a 1, after a 0 has been
read from OEM, or when the host writes a 0.
